' CARBONATOR.

Specification of Letters Patent.

. Application filed July 3, 1908. Serial No. 441,811. Y

To all whom it may concern:

Be it known that 1, Louis \V. Simiansounln'r, citizen of the United States, residing. at La Grosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful :lmprovements in ("urbonators, of which the following is a specification.

This invention has for its object a simple and efficient construction of-apparatus for earbonating beer or other liquids, and the invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

l igure'l isa longitudinalsectional view of in improved carbonating apparatus and, Figs. 2 and 3 are detail face views of the two different forms of diaphragms employed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved carbonating apparatus comprises a cylinder 1 of copper orany other suitable metal or material of any desired length and diameter, said cylinder being provided at one end with an inlet; pipe 2 and at its opposite end with an outlet pipe 3 for the carbonated beer. \Vithin the cylinder 1 are two sets of diaphragms, the diaphragms 4 of one set alternating with the diaphragms 5 of the other set, and said diaphragms being spaced from each other as shown and extemling parallel with each other and secured in place by any desired fastening devices. Each of the diaphragms 4 consists of av central solid portion 6 of any desired metal or material, and a circular rim portion 7 which is foraminous in the present. instance, such rim being perforated, although it is to be understood that it may be other wise formed to secure the )erforate or foraminous character. Eacho thediaphragms 5 of the other set is formed with a central foraminous portion 8 which may, as shown in the present instance, be constructed of wire meslnand a solid or impcrforatc rim portion 9. Itis to be particularly not d that r the foramlnous portion of-each screen in longitudinal alinement with the solid portion of the next or ad acent screen or draphragm and that the solid portion of each diaphragm is of greater superficial area than the foraminous 0r perforated portion of the next diaphragm. Hence the beer, as it passe through the apertures of one diaphragm will be formed into currents that wiltbe directed against the solid portion of the next diaphragm and be deflected thereby, and it is therefore obvious that as the beer tlows through the cylinder, it will-be caused to pursue a ircuitous course and thereby effect a thorough conuningling of the beer and carbonic acid gas. Instead of the wire mesh and perforated screens described above, all of the screens may be made of wire mesh or of perforated metal, but I prefer the above described construction.

Near the inlet the cylinder 1 contains a partition it). A preferably centrally located tapered screen 11 with its apex outcrmost is secured. to the partition it) and is preferably surrounded by a similar tapered or conical screen 12, to the apex of which an open ended tube 1-3 secured, as clearly illustrated in the drawings. Au inlet. pipe 1-1- is received within the outer end of the tube 13 and preferably the innermost end of the pipe 14: perforated, as shown. The gas pipe ll is connected to any suitable source of supply (not shown) of carbonic acid or other carbonated gas and contains a gas regulating device 15 of any conventional form and a pressure gage 16, by which the flow of gas into the cylinder 1 may be controlled at the desired or predetermined pressure. The cylinder 1 carries a pressure gage l7 and the outlet 3 carries a small testing cock 18 provided with a spiral tube, so that the beer may be tested as to the degree with which it is charged with the gasbefore it passes to the bottles or other receptacles;

In the practical use of my improved beer carbonating apparatus, it will be understood from the foregoing description in connection with the accom ninying drawing, that the beer flows in through the inlet pipe 2 and passes through the funnels 12 and 11, being mixed at this point with the gas flowingin through the pipe 1stwhich is directed as shown at the apex of the tapered funnel 11 and which is' mounted centrally of the in-' flowing stream of beer and thereby forced to impregnate the same to the best possible :nlvantage. instead of as shown. in the drawing, the perforated 1' pe 14 may extend through one or more of the screens, thus delivering the gas farther up in the receptacle. The beerand gas then flow, as above noted, through the two sets of screens 4t and 5, and a thorough commingling of the gas and beer is effected, the charged beer finally 5 passing out through the outlet pipe 3 to the bottling apparatus, or other receptacle. It will thus be seen that I have provided a very simple and efiicient beer earbonating apparatus which avoids the necessity of using a pump between the outlet pipe and bottling apparatus, and which will more completely m i-ngle the gas and beer than the ordinary air pump carbonating apparatus.

is claimed as new is:

1. A carbonating apparatus, comprising a cylinder with an inlet pipe and an outlet pipe and a Series of alternately arranged diaphragrns mounted within and extending transversely of the cylinder, one diaphragm being formed with an i'mperforate central portion and a foraminous rim portion, and the next diaphragm being formed with an imperforate rim and a foraminous central portion, the imperforate portion of one diaphragm facing and being in longitudinal alinement with the foraminous portion of .the next diaphragm.

2. A carbonating apparatus, comprising.

' a cylinder with an inlet and an outlet pipe Having thus described the invention, What tion and the next diaphragm being formed with an imperforate rim portion and a foraminous central portion, the impertorate portion of each diaphragm being in longitudinal alinement with and of greater superficial area than the foraminous portion of the next diaphragm.

A carbonating apparatus, comprising a cylinder, provided at one end with an inlet pipe and at its other end with an out let pipe, a series of foraminous diaphragms mounted within the cylinder, a tapered mixing screen mounted in said cylinder contiguous to the inlet pipe and formed with a sleeve projecting into and spaced from ihe walls of said inlet pipe, and a gas inlet pipe extending into the first named, inlet pipe and provided with a perforated discharge end projecting into said sleeve.

In testimony whereof I ailix my signature in presence of two Witnesses.
